修課人數限於80人, 因為疫情規定且本課程需要實體上課才能真正有效討論. 請真正想要學習並願意貢獻於區塊鏈的同學第一堂課來瞭解課程內容後再決定加退選, 我可以提供解決區塊鏈及其應用大部分問題的方法(包含目前無解), 需要花點力氣才能學好並有所貢獻! 歡迎挑戰(別踢館), 請準備好誠心正意地接受不同的觀念. 很多問題我可能沒聽過, 你清楚說明問題, 也許我也可以解決. 如果我一時解決不了, 相信我們改天可以解決. 疫情期間排座位恕無法旁聽, 為了落實學習, 不提供錄影, 請參閱投影片, 並自行記錄心得!

## Homework
* Download Bitcoin/OurChain source code, compile it, and run it.
* Suppose many people throw many-face dices in many rooms. The one with the hash value of the number thrown and room ID less than or equal to some number target wins, i.e. SHA256(number thrown, room ID) ≤ target. How do we estimate how many times the winner threw?
* Each team discusses how to build a paper tower with 10 A4 used paper in 10 minutes using only hands, with no tape, glue, knife … The higher, the better. Send a photo < 3MB and a text file, the smaller, the better, (to a blockchain) to prove your work.
